The T-shirt Dimensions Chart

My Gildan 500 T-shirt designs I ordered and measured, were about 1" less in width and length than the dimension chart. Not much difference. A different T-shirt design I've had for a few years, a different brand, is about the same dimensions as my Gildan 500 T-shirt designs.

T-shirt sizes are pretty much standardized. So they'll be closely within range of the dimension chart. But they will vary a little bit from manufacture to manufacturer.

So as a point of reference, any T-shirt sizes you already wear will very much have the same feel (size-wise) as these T-shirts.
